Product Overview 

Product Positioning 

The HP DeskJet 1220C is designed to be the printer of choice for small busi- 
nesses and offices that value printing on a wide range of media types and sizes. 
The HP DeskJet 1220C printer can print vibrant colors on paper up to 13" x 50" 
(330 mm x 1016 mm). It connects directly to IBM and IBM-compatible comput- 
ers through a parallel port or a Universal Serial Bus (USB) port, and connects 
to Macintosh 68040 or later computers through a USB port. The printer can 
also be shared on a network. 

Model and Serial Number 

The serial number and the model number are listed on the identification label 
located on the back of the printer. The serial number contains information 
about the Country of Origin, the Revision Level, the Production Code, and the 
Production Number of the printer. The label also contains power rating and 
regulatory information. 



Note These values vary by region. 

Technology Update 
Thermal InkJet Technology 

Thermal InkJet Technology is based on HP's disposable print cartridges. In 
each cartridge, there is a small reservoir, known as the firing chamber, filled 
with a tiny measure of ink. This ink is heated with a thin-film resistor layered 
above the firing chamber. As the ink heats up, it expands to form a bubble. The 
bubble expands until it bursts, at which point the ink is forced through the noz- 
zle located below the firing chamber and out onto the paper. This process is 
repeated up to 12,000 times per second, and creates residual heat in the resis- 
tor. A layer of silicon is placed above the resistor to cool it by transferring the 
residual heat away. 

HP black print cartridges (series C51645) contain 300 nozzles and HP color car- 
tridges (series C6578) contain 432 nozzles (144 per color). 

PhotoREt III 

Photo Resolution Enhancement technology enables DeskJet printers to pro- 
duce photo-quality color images. PhotoREt Ill's Color Layering technology 

1-2 Product Information 



combines small ink-drop-volume print cartridges, vibrant, fade-resistant color 
inks, new halftoning algorithms, and specially developed HP Premium Plus 
Photo paper to deliver outstanding image quality and performance. The 
increased capacity of HP DeskJet 1220C printers to place up to 29 drops of ink 
in a single pixel creates finer color control and produces five times the number 
of colors produced by PhotoREt II printers. 

ColorSmart III 

ColorSmart III enables the printer driver to scan the contents (text, graphics, 
and images) of pages to generate optimal settings for each document printed. 
ColorSmart III further extends ColorSmart technology with new image- 
enhancement tools: 

• HP SmartFocus-A new algorithm that improves image clarity in high-reso- 
lution files, as well as continues optimization for low-resolution images 
from the Internet or multimedia sources. 

• HP Automatic Contrast Enhancement (ACE)-Brightens colors and sharp- 
ens details in images captured under poor lighting conditions. 

• sRGB (standard Red, Green, Blue)-An industry peripheral color standard 
developed jointly by HP and Microsoft that improves color matching in 
peripheral devices that support the color standard. 

• Intel MMX/SIMD technology-Allows the driver to process media-rich data 
in parallel for faster processing of color and image graphics.

HP Express Exchange 



Through Customer Care Centers in the United States and Canada, customers 



1-24 



Product Information 



have the option to initiate Express Exchange. Under this option, customers 
may have a factory refurbished printer sent to them within 24 hours. 

1 The customer contacts the local HP Customer Care Center. A technician 
troubleshoots the situation and determines whether the printer has failed. 
If so, the technician refers the customer to the HP Service Center. 

2 A representative from the service center requests product and customer 
information. In some regions, collateral may also be requested. 

3 HP ships a refurbished replacement unit to arrive the next day; geographic 
distance might prevent next-day shipping. 

4 The customer sends the defective printer to Hewlett-Packard at HP's 
expense. Customers with on-site support service provided by HP should 
work directly with the local Customer Care Center instead of following the 
steps outlined here. Exchanged units carry the remainder of the original 
unit's warranty or 90 days, whichever is greater. The faster turnaround 
from HP Express Exchange minimizes downtime over traditional service 
programs that require the user to ship the failed unit to the manufacturer, 
and then wait for it to be repaired and returned. Because HP pays the ship- 
ping charges, the user incurs no hidden costs for the service.

Figure 2.2 Connecting via a USB Cable for Windows Users 

USB cables, such as an HP USB-Compliant Interface Cable (part number 
C6518A), must be purchased separately. 

For Windows 98 Users 

The latest IBM or IBM-compatible computers have USB ports that can be 
directly connected to the printer's USB port. After connecting the USB cable, 
the New Hardware Found Wizard should appear. If it does not, your computer 
is probably not configured to use USB. Use a parallel cable instead to connect 
the printer to your computer. 

1 Insert the HP Printer Starter CD into your CD-ROM drive. Do not click the 
printer installation icon. Proceed to step two. 

2 Turn off the printer and connect the USB cable.

Selecting Paper 



The HP 1220C printer prints on plain paper and many other types of media. 
Most plain paper used for photocopying yields good results. For more informa- 
tion see Printer Description and Features on page 1-4. 

• Do not use media that is damaged, curled, or wrinkled. Do not use media 
with cutouts or perforations or paper that is heavily textured or embossed. 

• Do not use multiple-part forms. 

• Load only one media type at a time into any of the trays. 

• Always load media print side down with the right edge aligned against the 
right edge of the tray. 

• Do not load more than 150 sheets or 15 envelopes into the main (bottom) 
tray at one time. For the alternative (top) media feed, do not load more 
than 10 sheets of media or 3 envelopes. Load only one sheet of paper into 
the rear media feed tray. 



Note You do not need to remove media from the main tray when you use the alterna- 

tive media feed. The printer checks for media loaded in the alternative media 
feed. If media is present, the printer picks the media from there without check- 
ing the main tray. 



Standard Paper 

You can load any standard paper size up to 13" x 50" (330 x 1016 mm) in the 
printer's main tray. Load the paper you normally use into the main tray. Load 
special paper into the alternative media feed. 

Custom Paper 

You can use custom or odd-sized paper with the HP 1220C printer, as long as 
the media dimensions are between the minimum (3.94" x 5.83", 100 x 148 mm) 
and maximum (13" x 50", 330 x 1016 mm) sizes. 

Envelopes 

You can print on envelopes using the main tray, the alternative media feed, or 
4-2 Paper Selection and Paper Loading 



the rear media feed. 



Note When you select a media type in Print Settings, the HP DeskJet 1220C auto- 

matically adjusts the cartridge-to-paper spacing. This reduces smears on thick 
media such as envelopes, cards, and postcards. 



Cards 

You can print on cards using the main tray, the alternative media feed, or the 
rear media feed. 

Thick Cards 

To print thick cards (0.5 mm, 0.02") or cards requiring a straight paper path, use 
the rear media feed slot at the back of the printer. Feed the cards into the 
printer one at a time. 

Labels 

Use Inkjet labels of sizes up to 330 mm x 1016 mm (13" x 50"), and ensure that 
they are in good condition. 

Transparencies and Slides 

Use transparency films that are designed to work with HP Inkjet printers, such 
as HP Premium Transparency Films. 

HP Special Paper 

To print high-quality images, use HP Premium Photo Papers and HP Premium 
Inkjet Papers, which are specifically designed to work with this printer, or use 
premium papers that are designed to work with Inkjet printers. 

• HP Premium Photo Paper is designed to produce photographic-quality 
printouts. 

• HP Premium Inkjet Paper is designed to enhance black or color printouts. 



Note If printing more than one page on transparency film or photo paper, the Resume 

Light blinks while the printer allows extra time for the ink to dry. Press the 
Resume Button if you do not want to wait for the ink to dry before printing the 
next page. 



Selecting Paper 4-3 



Loading Paper in Main (Bottom) Media Tray 

The main media tray is designed to hold the media type you use most often. It 
can hold up to 150 sheets of plain paper or 30 transparencies. 





1 Lift the Output Tray and extend the 
paper width and length adjusters to 
their outermost positions. 

2 Insert up to a 3/4" (19 mm) stack or 150 
sheets of paper, along the right side of 
the main tray, print side down, until it 
stops. 

3 Slide the width and length adjusters in 
to meet the edges of the paper. 

4 Select Print Settings and click 
Setup. Change the print settings to 
match the media size, type, source, and 
orientation and click OK.

Loading Paper in Alternative (Top) Media Feed 

The alternative media feed is designed to hold the various media types and 
sizes used for occasional printing. It can hold up to 10 sheets of plain paper or 3 
transparencies. 




Note 



Figure 4.2 Loading Paper in Alternative (Top) Media Feed 

You do not need to remove paper from the main tray when you use the alterna- 
tive media feed. The printer will check for paper in the alternative media feed. If 
paper is detected, the printer will pick paper from there and not from the main 
tray. 

1 Extend the Output Tray and slide the paper width adjuster to the outermost 
position. 

2 Lift the small flap on the Output Tray and insert a maximum of 10 sheets of

Loading Paper Through Rear Media Feed 



The rear media feed is designed for printing on thicker paper like card stock 
and photo paper without bending or warping. This media feed is specially 
designed to give you a straight paper path. 




Note 



Figure 4.3 Loading Paper Through Rear Media Feed 

To print thick cards or cards requiring a straight paper path, use only the rear 
media feed. Feed the cards into the printer one at a time. 

1 In HP's print settings dialog box, click Setup and select Manual Feed in 
the Paper Source box. Change other print settings, if necessary, and click 
OK. 

2 When the Resume Light blinks, insert media, print side up, into the rear 
media feed, making sure that the edge of the sheet is aligned with the align- 
ment mark at the side of the slot. Press the Resume Button to continue 
printing.

Clearing Paper Jams 




To clear the printer of any jammed 
paper, open the Access Door and pull 
the paper towards you. 



If you cannot reach the jammed paper, 
turn the knob at the back of the printer, 
remove the Cleanout Trough, pull out 
the jammed paper, and replace the 
Cleanout Trough. 



If you still cannot reach the paper, lift 
up the Output Tray, and remove the 
jammed paper from the main paper 
tray. 



Figure 4.4 Clearing Paper Jams 

Tips for Avoiding Paper Jams 

• Make sure nothing is blocking the paper path. 

• Do not overload the alternative media feed. The alternative media feed 
holds up to 10 sheets of plain paper or other media measuring the same 
thickness. The main media tray holds up to 150 sheets of plain paper. 

• Load media properly. 

• Do not use media that is curled or crumpled. 

• Always use paper that conforms to the media specifications.

Caution 



The printer does not require scheduled maintenance. Periodic cleaning, how- 
ever, enhances the look of the printer and keeps it in peak condition. Cleaning 
may also make it easier to diagnose problems. 

Clean the exterior with a soft cloth moistened with mild detergent and water. 



WARNING! Turn the printer off and unplug the power cable before cleaning the printer. 



Use only water and mild detergent to clean the printer, other cleaners or 
alcohol may damage the printer.

Cleaning the Print Cartridges 

Clean the ink nozzles of the print cartridge if the characters printed are incom- 
plete, or if dots or lines are missing from the printouts. This is a symptom of 
clogged ink nozzles resulting from prolonged exposure to air. 

Note Do not clean the print cartridges unnecessarily because this wastes ink and 

shortens the life of the print cartridges. 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Choose Printer Services and select Clean Print Cartridges. 

3 Follow the instructions on the screen to clean the cartridges. 

Pen Recovery Diagnostic Test 

If printouts have incomplete text or graphics that are not corrected by cleaning 
the print cartridges, use the Pen Recovery Diagnostic Test. The Pen Recovery 
Diagnostic Test is a three level cleaning procedure that attempts to clean 
blocked print cartridge nozzles. 

Level One 

Level One performs a light print cartridge cleaning. 

1 Hold down the Power Button while pressing the Cancel Button twice. 

2 Release the Power Button. 

3 Run the Nozzle Pattern Diagnostic Test (see page 6-62). Look for gaps in 
the Nozzle Pattern test. If no gaps are present, the print cartridge has recov- 
ered. If gaps appear, run Level Two of the Pen Recovery test. 

Level Two 

Level Two performs an intermediate cleaning routine. 

Note Do not use this Pen Recovery test unnecessarily. This test shortens the life of 

the print cartridges. 

1 Hold down the Power Button while pressing the Cancel Button twice and 
the Resume Button once. 



5-4 Printer Maintenance 



2 Release the Power Button. 

3 Run the Print Cartridge Nozzle Test. Look for gaps in the Nozzle Pattern 
test. If no gaps are present, the print cartridge is recovered. If gaps appear, 
run Level Three of the Pen Recovery test. 

Level Three 

Level Three performs an intensive cleaning routine that takes about 2 minutes 
to complete. 

1 Hold down the Power Button while pressing the Cancel Button twice and 
the Resume Button twice. 

2 Release the Power Button. 

3 Run the Print Cartridge Nozzle Test. Look for gaps in the Nozzle Pattern 
test. If no gaps are present, the print cartridge is recovered. If gaps appear, 
replace the print cartridge. 



Note Use this test as the last resort for recovering clogged print cartridge; it con- 

sumes a considerable amount of ink. 



Using and Caring for Print Cartridges 5-5 



Cleaning the Electrical Contacts 

Poor contact between the print cartridges and cartridge cradles may also affect 
the quality of the printout. When this occurs, try cleaning the print cartridges 
and cartridge cradles. 




1 Remove the print cartridge from the 
printer. 

2 Clean the electrical contacts on the 
print cartridge cradle with a dry cot- 
ton swab. 

3 Clean the electrical contacts on the 
print cartridge with a dry lint free 
cloth. To prevent the electrical con- 
tacts from damage, you should wipe 
the contacts only once. Do not wipe 
the ink nozzles on the print cartridge. 

4 Re-install the print cartridge. 



Figure 5.1 Cleaning the Electrical Contacts 

Tips for Maintaining the Print Cartridges 

• Keep the print cartridges sealed in the original packaging until you are 
ready to use them. 

• Keep opened print cartridges in the printer or sealed in a plastic bag. 

• Store print cartridges at room temperature. 

• Use a "first-in first-out" inventory process to avoid having expired print car- 
tridges in stock. 

• Power off the printer by pressing the Power Button instead of by unplug- 
ging the power cord. Powering off with the Power Button returns the Car- 
riage to the Service Station. The Service Station caps the print cartridge 
nozzles to prevent them from drying. 



5-6 



Printer Maintenance 



Print Cartridge Life 

Print cartridge life for both black and color print cartridges is 18 months. 



Note The color print cartridge life specification is based on an 8" x 10" (203.2 mm x 

254 mm) printable area with a 15% printing density. 



Identifying Print Cartridge Expiration Dates 

Using expired print cartridges may cause print quality problems. Several 
important dates concerning print cartridge life are listed below. 

• Install Before Date-Located on the print cartridge carton. This date is 
printed on the side of the box for color print cartridges and on the bottom 
of the box for black print cartridges. The cartridge has a 24 month shelf-life. 

• Manufacture Date-Since the cartridge has a 24 month shelf-life, the manu- 
facture date is exactly two years before the Install Before Date. 

• End of Warranty Date-A cartridge is under warranty for 90 days of use if it 
is installed prior to the Install Before date. The End of Warranty date 
(YYYY/MM/DD) is marked on the cartridge itself and is the last day that the 
cartridge is under warranty. The End of Warranty Date = Manufacture Date 
+ Shelf-life + 90 days. 

The printer will allow a print cartridge to be used in the printer for two and a 
half years (130 weeks) after the date the cartridge was installed. This is the 
expiration date recorded in the ToolBox (Expiration Date = Date Cartridge 
Installed + 130 weeks). In the event that a cartridge is installed (and accepted) 
in the printer after the Install Before date has expired, the expiration date 
recorded in the ToolBox will be the following: Expiration Date = Install Before 
date + 130 weeks. 

Changing the Print Cartridges 

Both print cartridges are installed in the same manner. 



Note When you install a new cartridge, the printer automatically aligns the cartridges 

by printing a page. Make sure your printer has a sheet of standard paper avail- 
able to perform the alignment. If you replace a cartridge during a print job, align- 
ment occurs after the print job is finished. 



1 Power on the printer and open the Access Door. The Carriage will move to 
the center of the printer. 



Using and Caring for Print Cartridges 5-7 



2 Flip up the print cartridge latch, grasp the top of the old print cartridge, and 
pull it up and out of its cradle. 




Figure 5.2 Changing the Print Cartridges 



3 Remove the new print cartridge from its package, and without touching the 
ink nozzles or the contacts, gently remove the tape covering the ink noz- 
zles. 








Figure 5.3 Removing Tape from Ink Nozzles 

4 Push the new cartridge down firmly into its cradle slot, and close the print 
cartridge latch. 

5 Close the Access Door. 



Note 



If you did not install a recommended print cartridge, or the print cartridge is not 
properly installed, the Carriage will return to the loading position, and the Print 
Cartridge Light will continue to blink. 



5-8 



Printer Maintenance 



Aligning the Print Cartridges 

The printer automatically aligns the print cartridges whenever you replace one. 
If the printout looks like the cartridges are misaligned, you can align them man- 
ually. 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Select Printer Services and choose Align Print Cartridges. 

3 Follow the instructions on the screen to align the cartridges. 

If the cartridges are still not aligned, conduct the Calibration Diagnostic Test. 

Calibration Diagnostic Test 

This test calibrates the print cartridges by aligning the cartridges, as well as 
optimizing the turn-on energy for the color print cartridge. 

1 Hold down the Power Button while pressing the Resume Button three 
times. 

2 Release the Power Button. The printer prints a Calibration Diagnostic test 
page. A green check mark to the left of each test, indicates that calibration 
was successful. 

See Calibration Diagnostic Test on page 6-64 for more information.

Troubleshooting Strategy 



This chapter is divided into two sections: Software Troubleshooting and Hard- 
ware Troubleshooting. 

Often, customers have printer problems that are the result of improper configu- 
ration, operation, or maintenance of the printer. Many of these problems can 
be diagnosed and remedied over the phone. Software Troubleshooting helps 
you ask customers the proper questions over the telephone and helps deter- 
mine when a customer needs to return a printer for repair. To begin trouble- 
shooting over the phone, see Software Troubleshooting on page 6-3. 

Hardware Troubleshooting requires the printer to be present to confirm or fur- 
ther diagnose the problem before repair. Follow the steps outlined in Hard- 
ware Troubleshooting on page 6-27 to efficiently and effectively diagnose 
hardware problems. 



Note Both sections contain decision trees to help you troubleshoot printer problems. 

Grayed boxes in the decision trees indicate that further information is provided 
on the pages following the decision tree.

Damaged File or Software Problem 

See below for possible causes. 



Software Troubleshooting 6-7 



If the printer previously worked with the same software program, try print- 
ing another file using the software. If you managed to print this file, the file 
you were previously trying to print might be damaged. If you have a backup 
copy of the file, try printing it. 

Try printing from another software program. If you can print from another 
program, your printer setup is correct. 

If none of the above solutions worked, this problem is likely caused by your 
software program's inability to properly interpret print settings. Check the 
Release Notes for known software conflicts. Otherwise, check your soft- 
ware program manual, or call the software manufacturer to get more spe- 
cific help for this problem.

Faded or Dull Colors 

Possible causes: 

Econofast Print Mode Selected? 

The EconoFast option uses less ink and prints at a faster rate; use it for print- 
ing drafts. To achieve better colored printouts, select Normal or Best Quality in 
the printer driver. 

Paper Type Print Settings Wrong? 

When printing on transparencies or other special media, select the correspond- 
ing media type in HP's print settings dialog box. 

Incorrect Media Type? 

Some paper types are not suitable for use with your HP DeskJet printer, see 
Selecting Paper on page 4-2. 

Print Cartridge Low on Ink or Clogged? 

Whenever print quality deteriorates, it is a good idea to perform the cleaning 
procedure and then a Self-Test. 

To clean the print cartridges: 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Choose Printer Services and select Clean Print Cartridges. 

3 Follow the instructions on the screen to clean the cartridges. 
To print a Self-Test: 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Select Printer Services and click Print a Self-Test Page. 

Check that all the lines are connected and printed properly on the Self-Test 
page. If the lines are broken, your print cartridge is probably out of ink. 
Replace your print cartridge with a new one. However, if you have recently 
replaced your cartridge, your cartridge is probably bad.

Caution 




Nothing Works? 

If none of these solutions work, this problem is likely caused by a failure in the 
printer or computer system. Send printer for repair. 

Bleeding Colors 

Possible causes: 

Print Setting Uses Too Much Ink? 

Some Paper Type settings (such as Transparency) and Print Quality settings 
(such as Best) require more ink than others. Choose different print settings in 
HP's print settings dialog box. Also, make sure that you have selected the cor- 
rect media type in HP's print settings dialog box. 

Incorrect Media Type? 

Some media types are not suitable for use with your HP DeskJet printer, see 
Selecting Paper on page 4-2. 

Refilled Print Cartridges? 

Refilling print cartridges is not recommended. 

The ink in the print cartridges has been carefully formulated by Hewlett-Packard 
to ensure superior print quality and compatibility with your printer. Damage to 
the printer or the print cartridge resulting from modifying or refilling the print 
cartridge is not the responsibility of HP. 

Nothing Works? 

If none of these solutions work, this problem is likely caused by a failure in the 
printer or computer system. Send printer for repair. 

Ink Smear 

Possible causes: 



Insufficient Drying Time? 

When printing documents that use a lot of ink, you must allow the document 
more time to dry before handling it. This is especially true for transparencies. 
Check immediately after printing whether smearing occurs in the printout. You 
can set dry time using the Printer control panel. 

Paper Type Causing Smearing? 

Some types of paper don't accept ink well, which causes the ink to dry more 
slowly and results in smearing. 



6-18 



Troubleshooting 



Page is Wrinkling with Too Much Ink? 

Color documents with rich, blended colors can use excess ink, which wrinkles 
the page during printing and causes smearing. Try using the Normal or Fast 
Print Quality setting to reduce ink, or use HP Premium Paper designed for ink- 
jet printing of vivid color documents. 

Excess Ink Crusted on Print Cartridge? 

An ink buildup problem can be solved by performing the cleaning procedure: 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Choose Printer Services and select Clean Print Cartridges. 

3 Follow the instructions on the screen to clean the cartridges. 

Nothing Works? 

If none of these solutions work, this problem is likely caused by a failure in the

Incomplete Text 

Possible causes: 

Print Cartridges Need Cleaning? 

Whenever print quality noticeably decreases it is a good idea to perform the 
cleaning procedure: 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Choose Printer Services and select Clean Print Cartridges. 

3 Follow the instructions on the screen to clean the cartridges. 

Print Cartridges have Poor Contact? 

Try removing and then reinstalling the print cartridges, making sure to snap 
them firmly into place. 

Print Cartridge Out of Ink? 

If cleaning the print cartridges doesn't help, your print cartridge may be out of 
ink. Replace the empty print cartridge. See Changing the Print Cartridges on 
page 5-7.

Jagged Text 

Possible causes: 



Wrong Type of Font Chosen? 

Some software programs offer custom fonts that have jagged edges when 
enlarged or printed. By using TrueType fonts you can ensure that the printer is 
able to print smooth fonts. When selecting a font, look for the TrueType icon. 

Printing Bitmap Text? 

If you are trying to print a bitmap image of text, it may have jagged edges when 
skewed, enlarged or printed. By using TrueType fonts you can ensure that the 
printer is able to print smooth fonts. When selecting a font, look for the True- 
Type icon. 

Incorrect Media Type? 

Paper that is heavily textured or does not accept ink well can cause graphics 
and text to print poorly.

Text or Graphics Cut Off 

Possible causes: 

Wrong Page Orientation Setting? 

The page orientation selected might not be correct for the document you are 
printing. 

Wrong Margin Settings? 

Make sure margin settings for the document do not exceed the printable area 
of your printer. 

Content Doesn't Fit on Page? 

Content that is cut off might be outside the printable area. Or, the size of the 
document you are printing is larger than the paper size in the main tray.

Meaningless Characters Printed 

Possible causes: 



6-22 



Troubleshooting 



Cable Connection is Poor? 

A common cause for nonsense characters is a poor cable connection between 
the printer and computer. 

To check the printer cable: 

1 Disconnect the cable from the printer and power on your printer. 

2 If your printer powers on, try connecting your printer to your computer 
using a different cable. 

3 If this does not work, reboot the system. Or, try connecting your printer to 
another system. 

System Needs to be Restarted? 

Turn off the printer and computer for a few seconds, turn them both back on, 
and then try printing again. 

Wrong Printer Selected? 

Check to make sure your HP DeskJet printer is selected as the current or 
default printer. 

1 In the Printers folder, click HP DeskJet icon. 

2 From the File menu, click Set As Default. 

Document File is Damaged? 

This happens occasionally. If you can print other documents from the same 
software package, try to print using a backup copy of your document. 

Conflicts with Port Sharing Devices? 

A probable cause for this problem is conflicts between the printer and other 
port sharing devices such as zip drives and other printers. Do not share the port 
with another device, or disable bi-directional communication and try again. To 
disable bi-directional communication: 

1 Open the Toolbox. Select Printer Status and click Preferences. 

2 Uncheck Enable Bi-directional Communication. 

Nothing Works? 

If none of these solutions work, this problem is likely caused by a failure in the 
printer or computer system. Send printer for repair. 



Software Troubleshooting 6-23 





Wrong Fonts 

Possible causes: 

Fonts Used Incorrectly in the Document? 

Make sure you correctly apply the font you have chosen. For example, in a 
paint program place the words in the desired size; don't enlarge by dragging 
and sizing. 

Font Available on Computer? 

The fonts used in the document might not match the fonts currently available 
in your Windows system. Or the type of font used is not designed to be printed. 
See if the font that is printing incorrectly is available in your software pro- 
gram's font selection box, and if it is a TrueType font. 

Wrong Printer Selected? 

Check to make sure your HP DeskJet printer is selected as the current or 
default printer. 

1 In the Printers folder, click HP DeskJet icon. 

2 From the File menu, click Set As Default. 

Nothing Works? 

If none of these solutions work, this problem is likely caused by a failure in the 
printer or computer system. Send printer for repair. 

Wrong Colors 

Possible causes: 

Colors are Completely Different? 

When colors are completely wrong (for example, when green prints as blue or 
yellow), the color cartridge might have run out of one or more colors of ink. 
The best way to check this is to perform a Self-Test to check the colors, fol- 
lowed by a cleaning procedure. 

To print a Self-Test: 

1 Double-click the Toolbox icon on the Desktop or in the Printer Group. 

2 Select Printer Services and click Print a Self-Test Page. 



6-24 



Troubleshooting 



To clean the print cartridges: 

1 Open the ToolBox by double-clicking the HP 1220C icon on your desktop or 
click Start, select Programs, followed by "HP 1220C Series", followed 
by HP 1220C ToolBox. 

2 Choose Printer Services and select Clean Print Cartridges. 

3 Follow the instructions on the screen to clean the cartridges. 

Colors are Gray or the Wrong Shade? 

• If colors are printing in shades of gray, Print in Grayscale is probably 
selected in HP's print settings dialog box. For color printing, select Imag- 
ing and uncheck Print in Grayscale. 

• If hue or tone of color is shifted, the wrong setting might be selected in 
HP's print settings dialog box. Select Imaging and make sure the color slid- 
ers are centered. 

For further instructions on changing print settings, see Changing Default 
Print Settings on page 3-4. 

Incorrect Media Type? 

Paper that is colored causes the mismatch in the printout. Try printing on plain 
white paper. 

Nothing Works? 

If none of these solutions work, this problem is likely caused by a failure in the 
printer or computer system. Send printer for repair. 

Slow Printing 

To enhance the performance of your printer, check the following: 

System Configuration 

• The minimum PC configuration for this printer is a Pentium-class computer 
with 16MB RAM (24MB RAM for Windows NT 4.0). 

• For printing of an A3 or B-size file, it is recommended that you have about 
50MB of free drive space in your system. Graphic intensive or photographic 
images may require more free space. 



Software Troubleshooting 6-25 



Port and Cable Settings (Windows 95 only) 

• Set port selection to ECP. Refer to the manual that comes with your PC sys- 
tem for more information on how to change your port setting or contact 
your computer manufacturer. 

• Use a IEEE-1284 parallel cable to enable bi-directional communication. 

PhotoREt 

You are printing on Photo Paper and have disabled PhotoREt. To lessen the 
time taken to print, turn the PhotoREt Option on (the default setting).

Power Cord 

Make sure the printer is connected to the power cord, that the power cord is 
plugged in, and that the power cord can handle 230V. 

To test the power cord: 

1 Power off the printer. 

2 Unplug the power cord and replace it with a power cord that works. 

3 Power on the printer. If the printer now works, then your power cord is 
faulty. 



Note The power cord cannot be repaired. If it is defective, it should be discarded or 

returned to the supplier. 



Measure Voltage of Power Supply Assembly 

1 Disconnect the Power Supply Harness Assembly from the Power Supply 
PCA. 

2 Use a multimeter to check the output voltage of the Power Supply Assem- 
bly. It should measure +19V (B+). 

3 Reconnect the Power Supply Harness Assembly when you are finished. 

4 Turn the printer off and the power the printer on again. 
To replace the Power Supply Assembly, see page 7-12. 

Measure Voltage of Logic PCA 

1 Use a multimeter to check the output supply voltage of the Arabian Analog 
ASIC on the Logic PCA. It should measure +5V (B+). 

2 Use a multimeter to check the input supply voltage of the Power Connector 
to the Output Ramp Motor Driver on the Logic PCA. It should measure 
+32V (B+).

Determining Error Trapped Codes 



Note 



The error code associated with the Error Trap condition is stored in non-volatile 
memory. 

If all three lights are blinking, press the Resume Button once. The LEDs will 
blink 32 times in a pattern of 0's and l's. The first four blinks determine the first 
digit of the error code, the second four blinks determine the second digit. Fol- 
low this pattern to determine all eight digits. The digits are binary encoded; if 
the Power and Resume Buttons blink, then the digit is a 0, if all three lights 
blink, then the digit is a 1. The following table will help you interpret the blink 
code:

Double-check your outcome by running a Single Diagnostic Test: 

1 Power on the printer. 

2 Press and hold the Power Button and press the Resume Button four times. 

3 Release the Power Button. The printer prints a Single Diagnostic Test page 
with the last error trapped code. 

If the Single Diagnostic Test page will not print, repeat the steps above, press- 
ing the Resume Button twelve times instead of four times. 



Note 



Always use the blink pattern to determine the error trap code before you per- 
form a Single Diagnostic Test; sometimes the printer is too damaged to print a 
Single Diagnostic Test Page. 



Error Trapped Codes 

The first digit is the Assert Type. 



Note 



The Assert Type code number and associated code may only be useful to firm- 
ware technicians. 



If the Assert Type is a or a 1, it is a Line Number Assert. Break the error 
code down in the following way: 

Example Error Code: 012B0872 = 012B I 0872. 

The first set of digits, 012B, is a line number. Convert the hexadecimal digit 
to decimal. It becomes line number 299. If you believe the printer problem 
is with the firmware, this information may be useful to a firmware techni- 
cian. 

The second set of digits, 0872, is the CRC encoded filename. Check the File 
Name CRCs section. The filename may help you make an educated guess 
where the printer problem is located or which firmware technician to con- 



6-42 



Troubleshooting 



Note 



suit for help. 

Do not rely solely on the CRC encoded filename to determine which part of the 
printer is faulty; the CRC encoded filename may be misleading. Use it as one of 
the many tools you have to troubleshoot the printer. These tools include the 
troubleshooting trees, the diagnostic tools, your knowledge of the printer, and 
your troubleshooting experience. 

• If the Assert Type is not a or a 1, then break the error code down in the 
following way: 

Example Error Code: C0020139 = C I 002 I 01 I 30. 

The first digit is the Assert Type. In the example above, C (HW) indicates a 
hardware problem. 

The second set of digits is the Assert Component ID. In the example, 002 
(MECH) suggests a mechanism error. 

The third set of digits is the Assert Product Type. In the example, 01 refers 
to a Venice product. 

The final set of digits is the error code. In the example, 30 indicates 
ERROR_MECH_CARRIAGE_BOARD_OFF and suggests which area of the 
printer to focus on for troubleshooting.

Note Open the Access Door when you suspect a print cartridge problem. Inside, you 

will see icons showing cartridge problems. If there is a problem, the yellow 
arrow on the cartridge cradle points to the icon that indicates the problem. 

Logic PCA Assembly 

To replace the Logic PCA, see page 7-10. 

Clean Print Cartridges 

Clean the print cartridges when lines or dots are missing from printed text or 
graphics. 

Note Do not clean the print cartridge unnecessarily because this wastes ink and

1 Double-click the Toolbox icon on the Desktop or in the Printer Group. 

2 Choose Printer Services and select Clean Print Cartridges. 



6-50 Troubleshooting 



Caution 



3 Follow the instructions on the screen to clean the cartridges. 

The ink in the print cartridges has been carefully formulated by Hewlett-Packard 
to ensure superior print quality and compatibility with your printer. Damage to 
the printer or the print cartridge resulting from modifying or refilling the print 
cartridge is not the responsibility of HP. 

Clean the Electrical Contacts 

If the carriage assembly does not move out of the home position or won't 
return to the home position, clean the electrical contacts on the print cartridge. 
Poor contact between the print cartridges and cartridge cradles may also affect 
the quality of the printout. 




1 Remove the print cartridge from the 
printer. 

2 Clean the electrical contacts on the 
print cartridge cradle with a dry cot- 
ton swab. 

3 Clean the electrical contacts on the 
print cartridge with a dry lint free 
cloth. To prevent the electrical con- 
tacts from damage, you should wipe 
the contacts only once. Do not wipe 
the ink nozzles on the print cartridge. 

4 Re-install the print cartridge.

Change the Print Cartridges 

Both print cartridges are installed in the same manner. If you believe your print 
cartridges are running out of ink prematurely, see Short Print Cartridge Life 
on page 6-53. 



Note 



When you install a new cartridge, the printer automatically aligns the cartridges 
by printing a page. Make sure your printer has a sheet of standard paper avail- 
able to perform the alignment. If you replace a cartridge during a print job, align- 
ment occurs after the print job is finished. 



1 Power on the printer and open the Access Door. The Carriage will move to 
the center of the printer. 

2 Flip up the print cartridge latch, grasp the top of the old print cartridge, and 
pull it up and out of its cradle. 




Figure 6.1 1 Changing Print Cartridges 

3 Remove the new print cartridge from its package, and without touching the 
ink nozzles or the contacts, gently remove the tape covering the ink noz- 
zles.

4 Push the new cartridge down firmly into its cradle slot, and close the print 
cartridge latch. 

5 Close the Access Door. 



If you did not install a recommended print cartridge, or the print cartridge is not 
properly installed, the Carriage will return to the loading position, and the Print 
Cartridge Light will continue to blink.

To replace the Flex Cable, see page 7-28. 

Short Print Cartridge Life 

Table 6.10 Short Print Cartridge Life 



Possible Causes 


Explanation 


Higher coverage rate than 
listed in the specifications 


Heavy concentrations of ink significantly reduce 
the number of pages a print cartridge can handle. 


Pages contain graphics 


Printing graphics requires much more ink than 
printing text. Whenever possible, print draft copies 
without the graphics. 


Selected print mode 


Best and Normal print modes use more ink than 
EconoFast mode. To maximize print cartridge life, 
print drafts of documents in EconoFast mode. 


Print cartridge has passed 
expiration date 


The print cartridge has passed its 18-month shelf 
life. Replace the print cartridge. Use a FIFO (First 
In-First Out) inventory process to avoid having 
expired print cartridges in stock. 


Printer is unplugged with 
the print cartridge out of 
its home position 


If you unplug the power cord to turn off the printer, 
the Carriage does not return to the home position. 
Always power off the printer by pressing the Power 
Button. This returns the print cartridges to the 
home position where the Service Station caps the 
print cartridge nozzles to minimize ink drying. 



Hardware Troubleshooting 



6-53 



Table 6.10 Short Print Cartridge Life 



Print cartridge may need to 
be restored 


Restore the print cartridge by running the cleaning 
routine. If print quality is not restored, replace the 
print cartridge. 


Excessive use of the print 
cartridge cleaning routine 


Restoring print cartridges by running the cleaning 
routine consumes ink. Avoid excessive use of the 
cleaning routine. 


Print cartridge stored 
improperly. 


Open print cartridges must be stored in the printer 
or in a print cartridge storage container. 


Refilled print cartridge 


Hewlett-Packard does not recommend or guarantee 
the print quality or print cartridge life of refilled 
print cartridges. Replace the print cartridge with a 
new HP print cartridge. 


Incorrect estimate of pages 
printed with the print car- 
tridge 


It is very easy to underestimate the number of 
pages printed.When counting pages per cartridge, 
be sure to count drafts that are thrown away. 


Faulty print cartridge 


Replace the print cartridge. If a pattern of faulty 
cartridges develops, the printer may be causing the 
print cartridges to fail. In this case, replace the 
Logic PCA. 


Printer hardware problem 


The Service Station may be faulty, or the printer 
may be damaging the print cartridges. If the prob- 
lem recurs, replace the Service Station components 
or the Logic PCA.

Figure 6.14 Single Diagnostic Test Page 

The Diagnostic Test printout contains the following information: 

• Printer Model 

• Serial Number 

• Born-On Date (Service ID)-See below for more information. 



Diagnostic Tools 



6-61 



• Firmware Revision 

• Print Total Engine Page Count 

• PCL Default Symbol Set-(For example, the code for the US fonts set is 
341.) 

• Manufacturing Tracking Code-(This information has no value for field 
repair.) 

• Error Code-If an error code (hex) number is displayed, it represents the 
last error that occurred regardless of whether the problem that caused the 
error has been fixed and the printer is presently operational. 

Born-On Date 

The Born-On Date (BOD), or Service ID, is automatically set when the first doc- 
ument is printed following the installation of the printer driver software. The 
BOD can be used to determine if the product is under warranty. 

The BOD is saved as a five digit code, YYDDD, where YY equals the number of 
years after 1990 and DDD equal the day of the year. For example, 09245 is the 

245 day of 1999 or, September 2, 1999. Therefore the warranty period began 
on September 2, 1999. Provide a six day grace period when determining if the 
printer is under warranty; this will allow for exceptions such as leap year calcu- 
lations and manual calculation errors. 

Note The Born-On Date is also valuable for identifying the printer usage rate. The 

Diagnostic Test identifies the total pages printed by the printer (Print Engine 
Total Page Count). Therefore you can determine the usage rate by identifying 
the page count per length of time: [page count / (current date - Born-On Date). 
Remember, the Reliability and Estimated Usage specification for the printer is 
5,000 pages per month. 

Nozzle Pattern Diagnostic Test 

This test prints a pattern to determine which nozzles, if any, are clogged or not 
firing. Look for gaps in the test pattern; these indicate faulty nozzles. 

1 Hold down the Power Button while pressing the Cancel Button eight times 
and the Resume Button four times.

2 Release the Power Button. The printer prints a Nozzle Pattern test.

Pen Recovery Diagnostic Test 

If printouts have incomplete text or graphics that are not corrected by cleaning 
the print cartridges, use the Pen Recovery Diagnostic Test. The Pen Recovery 
Diagnostic Test is a three level cleaning procedure that attempts to clean 
blocked print cartridge nozzles. 

Level One 

Level One performs a light print cartridge cleaning. 

1 Hold down the Power Button while pressing the Cancel Button twice. 

2 Release the Power Button. 



Diagnostic Tools 



6-63 



3 Run the Nozzle Pattern Diagnostic Test (see page 6-62). Look for gaps in 
the Nozzle Pattern test. If no gaps are present, the print cartridge has recov- 
ered. If gaps appear, run Level Two of the Pen Recovery test. 

Level Two 

Level Two performs an intermediate cleaning routine. 

Note Do not use this Pen Recovery test unnecessarily. This test shortens the life of 

the print cartridges. 

1 Hold down the Power Button while pressing the Cancel Button twice and 
the Resume Button once. 

2 Release the Power Button. 

3 Run the Print Cartridge Nozzle Test. Look for gaps in the Nozzle Pattern 
test. If no gaps are present, the print cartridge is recovered. If gaps appear, 
run Level Three of the Pen Recovery test. 

Level Three 

Level Three performs an intensive cleaning routine that takes about 2 minutes 
to complete. 

1 Hold down the Power Button while pressing the Cancel Button twice and 
the Resume Button twice. 

2 Release the Power Button. 

3 Run the Print Cartridge Nozzle Test. Look for gaps in the Nozzle Pattern 
test. If no gaps are present, the print cartridge is recovered. If gaps appear, 
replace the print cartridge. 

Note Use this test as the last resort for recovering clogged print cartridge; it con- 

sumes a considerable amount of ink. 



Calibration Diagnostic Test 



This test calibrates the print cartridges by aligning the cartridges, as well as 
optimizing the turn-on energy for the color print cartridge. 

1 Hold down the Power Button while pressing the Resume Button three 
times.

A green check mark to the left of each test, indicates that calibration was suc- 
cessful. For the numeric values associated with each test, print the Extended 
Diagnostic Test (see page 6-66). 

• Zero Column Adjust-The printer prints a black bar and scans across the bar 
to the edges of the paper to calibrate the print cartridge tolerance from the 
home position. 

• Optical Turn-On Energy (OTOE)-For maximum print cartridge reliability 
the color print cartridge must operate at the minimum amount of energy 
needed to fire all the nozzles. The OTOE test prints a series of rectangles 
and then scans the rectangular pattern to determine the lowest energy level

at which all nozzles fire. To determine the OTOE numeric value, print the 
Extended Diagnostic Test (see page 6-66) or print the OTOE Decoder docu- 
ment on a transparency. 

• Bi-Directional Print Cartridge Alignment-Calibrates the printing alignment 
of bi-directional carriage movement. 

• Coarse and Fine Vertical Alignment-Calibrates the vertical alignment 
between the black and color print cartridges. 

Extended Diagnostic Test 

This test identifies printer values stored in the non-volatile random access 
memory (NVRAM). For example, numbers include the OTOE and print car- 
tridge alignment values. 

1 Press and hold the Power Button while pressing the Cancel Button once 
and the Resume Button twice. 

2 Release the Power button.The printer prints an Extended Diagnostic Test

Removal and Replacement Strategy 



This chapter describes how to disassemble the HP DeskJet 1220C printer. To 
service certain parts of the printer, it may not be necessary to completely disas- 
semble the printer. However, it is important to remove parts in the proper 
order; for details on the order of removal, see the Disassembly Sequence. 

To reassemble the printer, repeat the steps in reverse order. 



Note Additional instructions for difficult or critical reassembly procedures are 

included. 



Removal and Replacement Tools 

You will need the following tools to disassemble the printer: 

• TORX® screwdriver with T-08, T-10, and T-20 screw bits or T-08, T-10 and 
T-20 TORX® screwdrivers. A magnetized screwdriver is helpful. 

• Needle nose pliers. 

• Small flathead screwdriver. 

Before You Begin 

Before you begin to disassemble the printer: 

1 Remove paper from the Input Tray. 

2 Remove print cartridges from the Carriage. To prevent ink from becoming 
encrusted on the print nozzles, place each print cartridge in a paper enve- 
lope and then seal it in a plastic bag. 

3 Power off the printer, remove the power cord, and wait at least five 

seconds. 



WARNING! To avoid electrical shock, completely discharge the capacitors before handling 
power supply components. To do this, power off the printer before you unplug 
the power cord. Wait five seconds before disassembling the printer. 



Removal and Replacement Strategy 7-3 



Tips for Disassembling the Printer 



• Many parts of the printer use plastic snap-fit technology. Use care when 
removing these parts; excessive force could break the snaps off of the 
parts. 

• Use the correct screws when reassembling the printer. 

Caution Electrostatic discharge (ESD) from your body can damage the Printer Circuit 

Assemblies (PCAs). Before removing any PCA, ensure that your work area is 
static-free; wear ESD dissipative straps, use an ESD mat, or work at an ESD 
protected workstation.

Removal, Replacement, and Calibration 



Calibrating the Printer 



The only calibration the HP 1220C printer requires is the pen-to-paper spacing. 
When properly calibrated, the printer provides optimum print quality without 
compromising media handling capabilities. Print quality improves as the print 
cartridges move closer to the media. However, if the cartridges are too close to 
the media, paper jams, print skew or print smear may occur. 

To maintain accurate pen-to-paper spacing, you must calibrate the printer 
whenever the Carriage Rod is moved or removed. Removal and replacement of 
the following printer parts affect pen-to-paper spacing and require calibration: 

Carriage Assembly/Carriage Rod 

Backbone Assembly 

Upper Paper Guide Assembly 

Drive Roller Assembly 

Trough- 1 Assembly 

Right Support Assembly 

Left Support Assembly 

Calibration Tool 

To calibrate the pen-to-paper spacing, use the Pen-to-Paper Spacing Calibration 
tool (PPS Calibration tool). The recommended tool is the HP Desk Jet PPS Test 
Tool, part number C6569A. However, you can also use the older models of the 
PPS Calibration tool that have a dial with a pointer hand. Calibration proce- 
dures for both tools are described below. 

How to Calibrate 
Before You Begin 

1 Remove the Cleanout Trough Assembly. 

2 Ensure the Pivot is fully raised; this is its normal position. 

3 Locate the gear on the right side of the Service Station. To unlock the Car- 
riage, turn the gear clockwise three revolutions. 



Calibrating the Printer 7-37 



4 Remove the black and color print cartridges. 

Using PPS Calibration Tool (part number C6569A) 




Figure 7.20 Calibrating the Printer 

1 Pull out the latch (la) on the PPS Calibration Tool; this will retract the 
tool's probe tip (lb) and prevent damage to the tool and the printer. 

2 Insert the PPS Calibration Tool into the color cartridge cradle and close 
the print cartridge latches. Make sure the Carriage can move freely. 

3 Move the Carriage to align the ESD clip on the color cartridge cradle with 
the fifth cockle rib to the left of the pivot. The Carriage will now be near 
the left end of the Carriage Rod. 

4 Gently push the latch on the PPS Calibration Tool to release the probe and 
measure the pen-to-paper spacing. It should read 55 +/- 10 mils. 

5 To adjust PPS, loosen the three silver screws that secure the Upper Rail to 
the Backbone Assembly. Insert a flathead screwdriver into the slot on the 



7-38 



Removal, Replacement, and Calibration 



Caution 



Upper Rail that is closest to the Carriage. Turn the screwdriver until the 
tool reads 55 +/- 10 mils. 

Do not loosen the black screws that secure the Upper Rail to the Backbone 
Assembly. The black screws have been specifically torqued to provide proper 
tension for PPS adjustments. 

6 Raise the PPS Tool latch and move the Carriage to align the ESD clip on 
the color cartridge cradle with the third cockle rib to the right of the pivot. 
The Carriage will now be near the right end of the Carriage Rod. 



7 Repeat steps four and five. 

8 Recheck your first measurement near the left end of the Carriage Rod; 
adjusting the right end of the Carriage Rod can affect the left side. Read- 
just the left end if necessary. 



Caution 



Caution 



9 Tighten the silver screws. 

Using the LVDT Calibration Tool 

1 Move the Carriage to align the ESD clip on the black cartridge cradle with 
the fifth cockle rib to the left of the pivot. The Carriage will now be near 
the left end of the Carriage Rod. 

2 Insert the LVDT Calibration Tool into the black cartridge cradle and close 
the print cartridge latches. 

Do not move the Carriage while the LVDT Calibration Tool is in the printer; you 
will damage the tool and the cockle rib. 

3 Ensure the probe tip of the tool is resting on the cockle rib and check the 
PPS measurement. The MP-1000 should read 55 mil +/- 10. 

4 To adjust PPS, loosen the three silver screws that secure the Upper Rail to 
the Backbone Assembly. Insert a flathead screwdriver into the slot on the 
Upper Rail that is closest to the Carriage. Turn the screwdriver until the 
MP-1000 reads 55 mil +/- 10. 

Do not loosen the black screws that secure the Upper Rail to the Backbone 
Assembly. The black screws have been specifically torqued to provide proper 
tension for PPS adjustments. 

5 Lift the trigger on the LVDT Calibration Tool and move the Carriage to 
align the ESD clip on the black cartridge cradle with the third cockle rib to 



Calibrating the Printer

the right of the pivot. The Carriage will now be near the right end of the 
Carriage Rod. 

Note Make sure the trigger of the LVDT tool is lifted up when moving the Carriage. 

6 Repeat steps two through four. 

7 Recheck your first measurement near the left end of the Carriage Rod; 
adjusting the right end of the Carriage Rod can affect the left side. Read- 
just the left end if necessary. 

8 Tighten the silver screws.
